(01.33-1265) This invention relates to a gauging attachment for tankscontaining fluids, and the prime purpose of my invention is to providean attachment whereby the gauging edge may be so positioned that themeasured distance from the gauging edge to the bottom of the tank isuniform for all tanks of the same capacities. Heretofore, tanks variedin the measured distance from the gauge hatch to the bottom of the tank,which is the measured vertical depth of the tank, and this variation wasas much as several inches or fractions of an inch, and consequently eachtank had to be separately calculated, and the mathematical computationswere frequently quite involved.

An object of my invention is to provide a novel gauging attachment whichcan be quickly and easily attached to the gauging hatch of a tank, andwhich may be adjusted so that the measured distance from the gaugingedge to the bottom of the tank is either a uniform number, or is a wholenumber, so that the mathematical computations to determine the capacityof a tank is simple.

Another object of my invention is to provide a novel gauging attachmentof the character statinexpensive Other objects, advantages and featuresof invention may appear from the accompanying drawing, the subjoineddetailed description, and the appended claims.

In the drawing:

Figure 1 is a side elevation of my gauging attachment in position on atank.

Figure 2 is a side elevation of my gauging attachment with parts brokenaway to show interior construction.

Figure 3 is a dissembled view of the mounting clamp.

Referring more particularly to the drawing, the tank I, preferablycontaining a fluid, is of usual and well known design and construction,and includes a gauge hatch 2. The tank is gauged through this hatch, allof which is usual and well known in the art. Heretofore, the gauger hasdropped the tape 3, into the tank, through the gauge hatch 2, and hasobserved the reading on the tape at the top of the gauge hatch, whichwould give him the vertical measured distance from top to bottom of thetank.

The gauge hatch 2, is relatively low and fre- 2 quently an accuratereading at the top of the gauge hatch was difiicult to achieve. Mygauging attachment 4 consists of a two piece clamp 5, 6, which encirclesthe gauge hatch 2!, and is bolted around the hatch by suitable bolts I,thus rigidly securing the clamp in position. The member 6, of the clampincludes a vertical guide member 8, the purpose of which will be furtherdescribed.

A separate clamp member 9, is fitted between the clamps 5, 6, and isbolted in position by means of the bolt II]. A tube II, fits between theclamp members 8, 9, and when the bolt I0, is tightened, this tube isheld against vertical movement. By loosening the bolt I0, the tube canbe adjusted vertically if desired. A pipe or rod I2, extends through thetube II, and is held against vertical movement by set screws I3. Byloosening the set screws I3, the pipe or rod I2, can be adjustedvertically.

A plate I4, is fixedly secured to the pipe or rod I2, adjacent the upperend and is called the gauging edge. The workman measures with his tape3, to the edge I5, and this edge is so adjusted on the tank I, that thereading from the edge I5 to the bottom of the tank will be a uniform, ora whole number, that is it will be uniform with other tanks of the samecapacity.

The pipe or rod I2, can also be tilted slightly when the set screws I3are loosened, thus leveling the upper edge I5 of the plate I4 since itis important that this gaging edge shall be horizontal. I

Having described my invention, I claim:
